A calibration rig (1), for calibrating a torque wrench (9), comprises a support structure (3) for supporting the torque wrench (9) during calibration. The support structure (3) comprises: a support member (7) which is free to move substantially vertically; means for applying a balance force (14, 15) to the support member (7), wherein the balance force acts counter to a force exerted by the weight of the torque wrench (9) when a handle of the torque wrench (9) is received by the support member (7); means for applying a measured torque (6) to the torque wrench (7); and means for resisting rotation (16) of the torque wrench (9) as a result of the applied torque. |
